About

Building things that work

I turn fiddly real-world rules — like California’s wage-and-hour laws — into tools people can actually use. My calculators rank at the top of Google for their searches, and I’m now bringing that same logic to mobile with Wagecop.

  • Python
  • C++
  • React Native
